Project description

nbodykit is an open source project and Python package providing
a set of algorithms useful in the analysis of cosmological
datasets from N-body simulations and large-scale structure surveys.

Driven by the optimism regarding the abundance and availability of
large-scale computing resources in the future, the development of nbodykit
distinguishes itself from other similar software packages
(i.e., nbodyshop, pynbody, yt, xi) by focusing on :

a unified treatment of simulation and observational datasets by
insulating algorithms from data containers

reducing wall-clock time by scaling to thousands of cores

deployment and availability on large, super computing facilities

All algorithms are parallel and run with Message Passing Interface (MPI).

For users using the NERSC super-computers, we provide a ready-to-use tarball
of nbodykit and its dependencies; see Using nbodykit on NERSC for more details.

Build Status

We perform integrated tests of the code, including all built-in algorithms, in a
miniconda environment for Python 2.7 and Python 3.4.

Installation

We recommend using the anaconda distribution of Python.

To obtain the dependencies and install a package on OSX or Linux, use

conda install -c bccp nbodykit

We are considering support for Windows, but this depends on the status
of mpi4py.
